Description

Acid rain can be devastating to aquatic ecosystems and
terrestrial areas. It not only affects naturally-occurring
surfaces, such as rocky surfaces of mountainous regions,
but manmade surfaces as well. Stones and metals used
in buildings, statues and monuments may be affected by
acid rain. Rates of erosion and weathering increase rapidly
depending on the degree of acidic rain. In this activity,
students expose naturally occurring and construction
materials to an acidic environment and compare the
reaction of these materials to those exposed to ‘normal’
rain (tap water). Sufficient materials for 15 groups.
Teacher’s manual and student copy masters are included.
